Mathematics

kumpel [21]3 years ago
5 0

y + 7 = -   \frac{2}{3}(x + 6) \\

y + 7 =  -  \frac{2}{3}x - 4 \\

Subtract sides -7

y =  -  \frac{2}{3}x - 4 - 7 \\

Thus ;

y  = f(x)=  -  \frac{2}{3}x - 11 \\

So the correct answer is (( A )) .

Answer:

number one.  186in^{2}  number two.  36cm^{2}

Step-by-step explanation:

FOR NUMBER ONE:

the area of a trapezoid formula is   \frac{a+b}{2} h where a and b are the bases and h is the height. so we have to add in the numbers into the formula

\frac{12+15}{2} * 6\\ = <em>81</em>

and the paralellogram formula is b×h.  where b is the base and h is height

15 × 7 = <em>105</em>

so the area of the figure is 81 + 105 is 186 in^2

FOR NUMBER TWO:

the area of the square formula is s^{2}.   where s is the side

4^2 = <em>16</em>

and for the paralellogram is b × h

4 × 5 = <em>20</em>

so the area of the figure is 16 +20 = 36 in^2

hope this helps! ;)

F(x) = -5 x + 10
Then
f(-2) = -5(-2) + 10
= 10 + 10

If the diameter of a circle changes from 18 cm to 6 cm, how will the circumference change?
olga_2 [115]
The circumference when the diameter is 18 = 18pi

The circumference when the diameter is 6 = 6pi

18pi/6pi=3

The circumference will become a third of what it was.

Hope this helps!
